Rotblat encloses a letter he wrote to the members of the Pugwash Committee, as well as the first part of the History of Pugwash (record 117519 and record 117520).

Regarding Joliot-Curie's signature on the Manifesto, Rotblat asks BR to confirm if there was a disagreement with BR about one or two sentences.

"The second point is of even greater importance. I seem to remember that when you asked me to help in preparing the first conference you made it clear to me that while you would accept help from any individual you would be against any association with an existing organization, and you had particularly in mind the W.F.S.W. Now Burhop has just written his own version of the history of Pugwash, which he makes out to be almost entirely started by the W.F.S.W., and in it he says that you welcomed support from for the W.F.S.W. and were prepared to work with them. I would be glad if you would let me know your views, so that the matter can be straightened out. As I mentioned to you over the phone, I am very disturbed about Burhop publishing his history at the present time. Apart from being strongly biased, it would only add ammunition to our 'friends' in the U.S. Senate."

Rotblat asks for enlightenment on BR's "Kennedy and Macmillan are worse than Hitler" remark.
